ABSTRACT:
Two parallel webs of wrapping material are advanced toward the inlet of a wrapping mechanism in a twin cigarette rod making, filter rod making or like machine adjacent a paster with two wheel-shaped rotary applicators which apply strips of adhesive to selected marginal portions of the respective webs. The applicators receive adhesive from discrete rotary adhesive supplying members which, in turn, receive adhesive from a tandem pump. The applicators are installed at a level below the wrapping mechanism to reduce the likelihood of contamination of such mechanism by sprays or droplets of adhesive. The webs are draped around discrete tobacco-containing or filter material-containing rods, and the adhesive-coated marginal portions of the webs are folded over the other marginal portions to form seams which extend in parallelism with the axes of the resulting cigarette rods or filter rods.
